We have a taobao shop: https://shop145257746.taobao.com And you can get some info from: www.c-sky.com Best Regards Guo Ren
Thx, Waldemar > I tried your patchset, the toolchain is not downloadable, empty > files in github. Thx for your feedback, the reason of this is our git-lfs out of bandwith. We've purchased 2-data-packs/month about 100GB/month. Now It've been solved, and I've tested it again. Please have a another try, and sorry for that. > Can the c-sky devboards be bought anywhere in Europe? Now we just sold it on taobao in china. But we are preparing the csky-qemu instead.

To be honest, I would not accept to run this random binary blob hosted on baidu.com on my machine. So I think it should: 1/ Be hosted in a more official location 2/ Not require to run as root 3/ Preferably come with the source code. Also, if it's using the JTAG, do you need some additional hardware than the board?
